Comment on "A de Haas-van Alphen study of the Fermi surfaces of superconducting LiFeP and LiFeAs"

TL;DR

This paper clarifies the disagreement between de Haas-van Alphen measurements and ARPES results on LiFeAs, emphasizing the importance of accurate interpretation of experimental data in understanding its Fermi surface.

Contribution

It provides a critical commentary correcting the misinterpretation of experimental data on LiFeAs's Fermi surface by previous studies.

Findings

Reveals the discrepancy between dHvA data and ARPES results.

Highlights the importance of careful data analysis in Fermi surface studies.

Corrects the understanding of LiFeAs's electronic structure.

Abstract

In a recent preprint Putzke et al. argued that their dHvA data on LiFeAs are in good agreement with DFT calculations and contradict our ARPES results. Here we show that the situation is just the opposite.
